Zombie cancer cells eat themselves to live
Date:4/5/2014

cally, when PUMA is absent, it doesn't matter if autophagy is inhibited because without the communicating action of PUMA, cancer cells continue to survive.

The finding has important implications. First, it demonstrates a mechanism whereby autophagy controls cell death. And second, the study further reinforces the clinical potential of inhibiting autophagy to sensitize cancer cells to chemotherapy.

"Autophagy is complex and as yet not fully understood," Thorburn says. "But now that we see a molecular mechanism whereby cell-fate can be determined by autophagy, we hope to discover patient populations that could benefit from drugs that inhibit this action."
